Create a validator script in Jira Cloud

Damla Naz Yilmaz

If the user is already set as assignee somewhere in the project, he should not be able to transition another issue. therefore Iwould like to write a script validator. 
I already tried something like
 issue.assignee.includes(user.accountId).
But I was not succesfull.Does one of you have an idea and can help me

I am not sure I understand what you are trying to do here.  The way I read it is:

If a user is assigned issue X then they are not allowed to do a transition on issue Y.

Is that right? 

It's quite an unusual requirement, I would expect something more like "only the assignee of Y can transition Y"

I can't tell why your code doesn't work without being clear on what it is trying to achieve.
